Crossfire (commonly abbreviated as CF) is a tabletop miniatures wargame designed by Arty Conliffe and first published in 1996, later supplemented by "Hit the Dirt" containing a number of rules clarifications and scenarios.
Crossfire was originally designed to allow for company-sized battles and World War II scenarios.
As a consequence, CF works only properly on tables where much terrain is used in order to allow movement unseen by the opponent.
CF in its basic form is mainly concerned with infantry combat, leaving not much room for the employment for AFVs.
Others see it as variable ie urban combat would be denser than fighting at long range in the country side.
